Cold Junction Compensation Method
Conditions of Use: The Input Type must be thermocouple or non-contact
infrared temperature sensor.
Function: This parameter allows you to specify whether cold junction
compensation is to be performed internally by the controller or to be
performed externally when the Input Type setting value is 5 to 22, 24, or 25.
The cold junction compensation external setting is valid when the temperature
difference is measured using two thermocouples or two non-contact sensors.
